New Dwarf character model has a little secret...

So... I was showing my wife the new models and I happened to notice this, plain as day. At first I chalked it up to my mind being in the gutter or something, but the shape... the vein... I mean it almost looks intentional although it's likely an elbow or back of a knee it's still quite dubious.

EDIT: I should clarify, I mis-wrote the title, this is in fact, the old model being shown next to the new model. My apologies.
